That call, however, was never sent; for at that moment the mind of Mentor of Arisia flooded the group.
"Children, attend! This intrusion is necessary because a matter has come up which will permit of no delay. Boskonia is now launching the attack which has been in preparation for over twenty years. Arisia is to be the first point of attack. Kinnison, Tregonsee, Worsel, and Nadreck will take immediate steps to assemble the Grand Fleet of the Galactic Patrol in defense. I will confer at length with the younger Kinnisons.
"The Eddorians, as you know," Mentor went on to the Children of the Lens, "believe primarily in the efficacy of physical, material force. While they possess minds of real power, they use them principally as tools in the development of more and ever more efficient mechanical devices. We of Arisia, on the other hand, believe in the superiority of the mind. A fully competent mind would have no need of material devices, since it could control all material substance directly. While we have made some progress toward that end, and you will make more in the cycles to come, Civilization is, and for some time will be, dependent upon physical things. Hence the Galactic Patrol and its Grand Fleet.
"The Eddorians, after ages of effort, have succeeded in inventing a mechanical generator able to block our most penetrant thoughts. They believe implicitly that their vessels, so protected, will be able to destroy our planet. They may believe that the destruction of our planet would so weaken us that they would be able to destroy us. It is assumed that you children have deduced that neither we nor the Eddorians can be slain by physical force?"
"Yes—the clincher being that no suggestion was made about giving Eddore a planet from nth space."
"We Arisians, during an equally long time, have been aiding Nature in the development of minds much abler than our own. While those minds will not attain their full powers until after many years of work and study, we believe that you will be able, immature as you are, to use the Patrol and its resources to defend Arisia and to destroy the Boskonian fleet. That we cannot do it ourselves is implicit in what I have said."
"But that means ... this is the big show, then, that you have been hinting at so long?"
"Far from it. An important engagement, of course, but only preliminary to the real test, which will come when we invade Eddore. Do you agree with us that if Arisia were to be destroyed now, it would be difficult to repair the damage done to the morale of the Galactic Patrol?"
"Difficult? It would be impossible!"
